- acorpo'ration of New York Agitation July 7, 1953, Serial No. 366,474 10 Claims. (01. 30-68) This invention relates to a novel safety razor having a body arranged for gripping in the users hand, and not requiring aprojecting"handle. 'The invention razor is particularly designed for dry shaving of excess, unwanted hair from the limbs and arm pits.

Theusual safety razor comprises a body having an elongated'projecting handle and a head or otherguard means-arranged to clamp a razor blade in predetermined relation on the razor body with the blade edges at least partly exposed for cutting engagement with the hairs. These razors are designed particularly for shaving of the face where the angle of the razor blade to the skin and hair is not only important, for safety and comfort, but also difficult to control due to the varying facial contours. Experience has indicated that the blade angle can be most effectively controlled and maintained by providing an elongated handle extending substantially normal to the general plane of the razor blade.

Safety razors have become increasingly popular with women for removal of excess or unsightly hair from) the limbsand armpits, particularly prior to dressingin sleeve-,

less gowns or before donning sheer stockings. The usual projecting handle type of safety razor can be used for these purposes but is clumsy to handle and diflicult 'to maneuver, particularly as such shaving of the limbs, etc.

is done only at infrequent intervals and not as part of:

a daily routine. On the other hand, most men', shave daily or every other day and thus become accustomed to handling the razor, so that proper positioning of the handle becomes more or less automatic.

In view of the foregoing, there has long been a need.

for a simple, eflicientrazor particularly designed for use by women in dry shaving hair from the limbs, etc., and which is easy and non-complicated to handle.

To this end, the present invention provides a safety. razor which is characterized by the absence of the usual handle and comprises a body which can be readily gripped in the hand to, draw the blade over the skin. A feature of, the razor is the readily and easily effected assembly and disassembly of its parts.

More particularly, the bodyvhas a longitudinally recessed:

wall withtransversely spacedblade engaging projections agaiiist which theblade is held by1a removablehead or guard; shaped to deform the blade into the recess with the blade edges at a predetermined angle. ,The' guard has blade positioning abutmentsand a post projectible into the razor'body. This post has latching means on its free end engageable with a releasable latching element movably mounted in the razor body. The guard 'isaut' m'atically' latched to the body" by positioning the'gpard overablade in the'b'ody wall recess and forcing the guard toward the body tointerengage the spring biased latching elementf'with the latching means on the guard post.

Foran understanding of the invention principles, reference is made tot he following descriptionofjatypical embodiment thereof as illustrated in the accompanying drawing.

The innermost ends of rails 53 are integrally joined by an inturned lug portion 54 having a latching lug 55 having a double bevelled outer end 56. Projecting from the other side of lug 54 is a spring seating pin 57 engageable in one end of a coil spring 60 having its opposite end seated in recess 38. Coil spring 60 biases latching bar 50 outwardly, thus moving latching lug 55 somewhat into the cylindrical space defined by wall portions 34. Latch bar 50 and spring 60 are positioned in place before outer wall 21 is assembled to body 20. The upper edges of walls 33 cooperate with wall 21 to guide bar 20.

When guard 40 is pressed against a blade in recesses 40 and post 45 projected through opening 31, the bevelled edges 48 of a lug 48 cooperate with the bevelled edge 56 of lug 55 to force bar 50 inwardly, compressing spring 69, As lugs 47 pass beyond lug 55, spring 60 forces bar 50 outwardly to engage lug 55 beneath the adjacent lug 47 to releasably latch guard 40 to body 20. By pressing inturned lug 52 inwardly, the latching engagement is released so that the blade and guard may be disassembled from body 41.

In use, body is merely gripped in the hand and moved in either or both directions, by short or long strokes transversely of the length of the blade, thereby drawing the respective or both blade edges over the section of the skin acted upon for cutting the hair projecting therefrom, irrespective of whether unidirectional or reciprocating strokes are applied by the user. By virtue of the locational disposition of the blade and the respective blade edges on the body as shown and described in the illustrated embodiment, both blade edges may be utilized for speedy cutting action by reciprocation of the body 20, without reversing the hand grip thereon.

While a specific embodiment of the invention has been shown and described in detail to illustrate the application of the invention principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
